B. Hardware System Components

The functional model for the monitoring system of electric

energy consumption has been initially implemented for these

groups of consumers from Tritium Removal Installation

presented below:

-Compressor - K301

-General Power plant - TGD

-Generator - GE

Electrical parameters of the three consumers are acquired by

the power devices, Power Meter 710 with RS 485 network

connected to the Operator Station Monitoring System.

Mounting the Power Meter 710 was made in existing

switchboards Electrical Room from Tritium Removal

Installation. The electrical connections on the current measurement were accomplished by current transformers.

Also, the connection between the computer and Power Meter PM 710 was achieved using Power Logic EGX100

gateway module.

From a single building to a multi-site enterprise,

PowerLogic Web-Enabled Network Components provide fast,

reliable serial line to Ethernet connectivity in the most

applications.

PowerLogic Ethernet Gateways are available in two models

- EGX100 and EGX400 -providing direct connection to

Ethernet-Modbus®/TCP networks to make energy and power

monitoring information available over local and wide area

networks.

The EGX100, used in our application on tritium removal

installation, provides low-cost, reliable, Ethernet to serial-line

connectivity in a compact, DIN-rail mounted package. Enabled

by Power over Ethernet (PoE IEEE 802.3af), the EGX100

simplifies installation by eliminating the need for power

supplies plus provides a Web-based interface for configuration

and diagnostics.

The PowerLogic EGX100 Ethernet gateway helped us to

reduce the cost and complexity of connecting, configuring and

managing a network of intelligent meters, sensors and other

remote instruments [3].

The entry-level PowerLogic EGX100 enables users to

configure Ethernet and serial communication parameters, add

devices to a network and perform troubleshooting through a

web interface with detailed diagnostics. The PowerLogic

EGX100 supports 10BaseT and 100BaseTX and is suitable for

a wide range of applications including:

-Energy efficiency and cost control – Access usage

consumption from piped utilities and power equipment data

from power meters, circuit breaker trip units, programmable

controllers, drives and protective relays.

-Sub-billing and cost allocation – Add devices across a

TCP/IP network even if the building management system only

has a Modbus serial interface.

-Power distribution – Applied directly to power distribution

equipment and monitor and control devices that do not have a

native Ethernet communications port

-Building automation – Initiate a direct Ethernet connection to

the existing LAN/WAN configuration and maximize the return

on the investment.

-Factory automation – Obtain a full view of the power system

with remote monitoring and increase system performance on

alarms and data transfers. In Figure 1 is presented a block

diagram with EGX system architecture with connections

between computer and Power Meter 710 used in Tritium

Removal Installation.

Figure 1: EGX100 system architecture

Model PM710 meters offer a standard RS-485

communication port that allows data to be uploaded to

software for viewing and analysis. The port offers 2-wire

connection, operates at speeds up to 19.2 bauds, and supports

Modbus RTU protocol [5].

Also the PM710 meters are compatible with PowerLogic

facility-level or enterprise-wide power and energy

management systems. Real-time and min/max data can be

automatically retrieved for analysis at the system level,

compatible with PowerLogic ION Enterprise, PowerLogic

System Manager, PowerLogic PowerView and PowerLogic

Tenant Metering software. Modbus compatibility supports

integration with building automation, SCADA and other third-

party systems.

Metering is performed by zero-blind sampling and all inputs

are at the 32 samples/cycle with a data update rate of 1 second.

The meter offers a range of instantaneous RMS, power,

demand and energy measurements suitable for real-time

monitoring, energy management and sub-billing purposes.

In Figures 2 and 3 are presented front views of the PM 700

series.

All models PM 700 series offer also the total harmonic

distortion measurement (THD) on voltage and current, per

phase and min/max.

C. Software System PowerView

PowerView power monitoring software simplifies system

and device configuration by polling the network for

compatible PowerLogic devices. Connection and data logging

begins automatically at factory preset interval settings, which

are user configurable.

The software allows tracking real-time power conditions

and performing remote monitoring of electrical equipment or

installations at key distribution points across the electrical

network.

Software is easy-to-use selective and scan component for

quick and easy device detection, also select up to 32 devices to

add to the system – or manually add/delete devices.

The onboard device logging or PC-based logging

(depending upon device capabilities) begins automatically at

default or user-defined intervals.

We use Microsoft SQL Server 2005 Express Edition with

Advanced Services database with backup/restore capabilities

for reliable database management.

Real Time System is used to view the key points of

distribution in the electrical system. Measured quantities

include current, voltage, power factor, energy, power required

and total harmonic distortion (THD).

For an electrical appliance, the information stored in the file

daily report is presented below:

-address of the measure

-measuring point name

-date and hour, minute, second

-active energy- sum of the three phases

-reactive energy- sum of the three phases

-cost of energy for the three phases

-active power at that time for the sum of the three phases

-reactive power at that time for the sum of the three phases

-maximum voltage on R, S, T phases

-active and reactive power on phases R, S, T

-active and reactive energy on phases R, S, T

Viewing and printing system provided the following types

of reports:

-Specifically Report - 8 hours (or 12 hours)

-Daily report (24 hours)

-Monthly Report

-Annual report

To achieve the monitoring software was required the Power

View initial configuration and equipment used by Power Meter

PM 710 and EGX-100 module for connecting the computer to

the module PM 710.

Initial IP address was set via module PM 710 and the Start

Scan command is given, with view system configuration and

related modules.

We used the command "Report Builder" to build and

generate reports of measurements and graphs in Microsoft

Excel (Figure 6 and 7).

Standard reports include:

-General Measurement - models trend to use electricity, energy

or any other parameter required logged.

-Consumption of energy per day, energy consumption per hour

- analysis kilowatt / hour measured in cost allocation purposes.

-THD-quantitative - measuring, analyzing and comparing the

total harmonic distortion

-Time-use (TOU) - set up to three programs each with 10

periods of TOU energy storage, weekend, special days, and

holidays.

III. CONCLUSIONS

The PowerLogic system with PowerView software used in

Tritium Removal Installation allows the measurement and

monitoring of power and energy consumption at any level

from a supply network and power distribution.

Energy management of an installation (consumption in

different sectors) is the process of monitoring, coordination

and control of these inputs in order to ensure efficient

consumption of energy by reducing energy losses and thus

minimize energy costs.

Also, the research in the field of monitoring power for

important consumers within a technological installation,

represents an important contribution to the economic

development by means of increased energy efficiency of the

entire energy chain.
